To all whom itmay' concern: I

'Be it knownthat I,1-ARTH R M; YocE L, 7 a citizen of the United-"States, residingiat attachment, which may be applied withoutalteration to the conventionalform of man- ,Centralia, in the county of Lewis and State of Washingtomfhave invented certain new; .i and useful Improvements in Flushing Mechanisin of which the following is a specifica This invention relatesto fiushingappa ratus, and more particularly has for its ob ject the provision of an automatic flushing ually operated flushing apparatusl j The invention has for its primary ob ect the provision of an attachmentwh ch is simple in construction, readily applied, efficient; v for the purpose desired and strong and r durable in use. V

A further obj ect'of thefinvention, resides in the provision ofa movable fluid containing cylinder, having a piston working there- 1 in land connected with the cistern, so that when the device' is operated, the return of;

the cylinder isretarded by means of the fluid contained therein. r

All of the foregoing together 'with addi- A i ional advantageous detail'and a-rra-ngein'lent vofparts ofithelpreferred embodiment of my n scriptionliereinafter contained, when read inconnection with the accompanying drawings forming apart hereof, and wherein '3 r a n understand ng of the present mprovements. liteferring t0fthedraw1ngs: V

parts in the several views, 1 'isia :c'istern,

having a pipe connection 2, communicating f with the ilushing'bowl 3, andtisa pivoted seat. The construction as 'abovermentioned is of the conventional fornras now being used and forms no part of thepresent invention, with the exception that it serves as 7 means for illustrating the arrangement of the attachment thereon. T

5 is a movable cyl'nder, having a weight 6 attached thereto means of a connecting rod 7WVll1Cl1-1S screw-threaded. so asto allow "for the adjustmentrof the weighti 'Pivotally secured to the :cylinder isiaklever 8 jconnected to a hinge 9 Which-is fastened to cylinder, such as heavymachine-oil, etc. The rod 12is connected to a chainult by a suitable connection arranged at 15, the chain extending to the-icistern andubeing connected with theiiushing valves;

In Fig. 2I-have shown a somewhat modi fied form, wherein the attachment is applied to a rodactua-ted cistern; and inthis particular construction,"lgis-a cistern, con- 7 nected withthe' flushing bowl 2-, 3 isa movable cylinder supplied' with the weight 4:, and the flexible connectingmeinber 5 which is connected at'fi to the piston rod. The

construction of the attachment asthus far described, is identical to that used in the prior embodiments. The supplemental attachment used with the rod actuated cistern,

consists of a weighted arm 7 connected at one end with'the flexible member" 5", which is pivotally' supported at '8" and supplied with a weight 9, which weight is supported Connected with carriedby a pivoted link portion 12' for operating the flushing valve. 7

It will be seen-that the operation of the attachment as shown in Fig. 1 is as fol- .lowszf Assuinin'g that'the seat 'tis down, the movable cylinder. with itsweight 6 will v "be held out of engagement with the floor, v ,rod and the cistern flushing valve, as illusi tratedin Fig-.2. i i

thereby causing 'a slack in? the flexible unemdescent of thepiston 10 into the fluid 13,

the fluidpassiiigithrough the ports ll into are t oe e r. p s-1h FYIW ePP When the seat is released and allowed to be the piston is stopped in its downward movement by means of the flexible member 14.

swung upward, the cylinder 5, will be abruptly lowered, thereby causing the piston 10 to be carried with the same, which action, will cause the flexible means 14 to actuate the flushing valve. The pistonlO is slowly retracted, the fluid 10 passing back through the ports 11 to the bottom of the cylinder 5 and when so arranged is ready for the next operation.

Referring to the modified form as shown in Fig. 2, it may be stated that the operation thereof is the same as that above described,

but in order to provide for means of suflicient weight for retracting the piston, there is provided the weighted arm, which by reason of the weight 9, will cause the piston to be slowly retracted. may be also used in other cisterns wherein the siphon is not of sufiicient weight to retract the piston.

In accordance \Vltllilllfi patentstatutes, I

I claim is t I ,1. In a flushmg mechanism of the character described, the combination of a movable cylinder, a connecting rod secured to said 7 cylinder, a weight adjustably mounted upon the lower end of said rod, said cylinderbeing adapted to contain a quantity of heavy fluid matter, a piston rod projecting into the upper end of said cylinder, a piston carried upon the inner end ofsaid rod and having ports formed therein, said piston rod being adapted to be connected to a valve mechanism, means for raising said cylinder and weight and holding the same in elevated position for a predetermined time,

whereby said piston rod and said piston will move downwardly toward the lower end of said cylinder, ,while the fluid will pass through said ports above said piston, and said cylinder being adapted to be lowered suddenly thus causing the weight of the fluid upon the piston to draw downwardly upon the piston and piston rod for tripping a valve mechanism, although said fluid will gradually pass through said ports below said piston.v

2. In a'fiushing mechanism of the character described, the combination of a cistern having avalve mechanism, a flushing bowl,

means connecting said cistern to said bowl,

Such a construction,

a seathingedly mounted upon said bowl, a hinge secured to said seat and projecting therebeyond, a lever pivotally mounted upon said hinge and projecting therebelow, a cylinder hingedly secured to the free end of said lever, a rod connected to said cylinder, a weight adjustably mounted upon said rod, whereby said cylinder and weight will normally draw downwardly upon the lever for elevating the seat for a predetermined distance, a piston rodextending into the upper end of said cylinder, a piston carried upon said rod, said piston having ports formed therein, said cylinder being adapted to contain a quantity of comparatively heavy liquid material, whereby as said seat is pressed into a substantially horizontal position said hinge and lever will lift said cylinder and weight, thus vallowing the piston rodand piston to gradually settle toward the lower end of said cylinder by the passage of the liquid through said port, and said weight being adapted to abruptly draw the cylinder downwardly when the pressure is removed from the seat, thus exerting a pull upon said piston rod, said piston rod being adaptedto be connected to the valve mechanism of said cistern, for actuating the same as it is moved.

3.: In a flushing mechanism of the class described, the combination of a movable cylinder, a piston rod projecting into said cylinder, a piston carried upon the inner end of said rod and having ports formed there in, said piston rodbeing adapted to be connected to a valve mechanism, means for raising said cylinder and holding the same in an elevated position for a predetermined time, thus allowing said piston rod and said piston to move downwardly toward the lower end. of said cylinder, while the contents of the cylinder will pass through said ports and said cylinder being adapted to be lowered suddenly, thus causingthe' contents of the cylinder to force the piston downwardly for trippinga valve mechanism, although said contents will gradually pass through said ports below said piston.

4. In a fiushingmechanism of the character described, the combination of a cistern having a valve mechanism formed therein, a flushing bowl, means connecting said cistern to said bowl, a seat hingedly connected to said bowl, a hinge secured to said seat and projecting therebeyond, a lever pivotally mounted upon said hinge and projecting therebelow, a cylinder hingedly secured to the free end of said lever,said cylinder normally drawing downward on said lever for elevating the seat for a predetermined distance, a piston rod extending into the upper end of said cylinder, a piston carried uponsaid rod, said piston having ports formed therein, whereby as seat is pressed 1nto a substantiallyhorizontal position, said lever will lift said cylinder, thus allowing the piston rod to gradually settle toward the lower end of the cylinder by the passing of the contents of the cylinder through said ports, and said cylinder drawing down- \vardly suddenly when pressure is removed tuating the same when said cylinder is 10 lowered.

In testimony whereof I aifix my signature in presence of two witnesses.
